Liquefied petroleum gas is a common energy source in our daily life, mainly composed of methane and propane. Although they are all liquefied gases, there are some differences between methane and propane in terms of chemical properties, uses and storage methods.

methane and propane differ in chemical structure. Methane is composed of one carbon atom and four hydrogen atoms, and its chemical formula is CH4, which is the simplest alkane compound. Propane, on the other hand, consists of three carbon atoms and eight hydrogen atoms, with the chemical formula C3H8, which is larger than methane because it contains more carbon atoms.

methane and propane differ in the way they are burned. The gas produced by methane combustion is only carbon dioxide and water, the combustion efficiency is high, and there is no exhaust pollutant emission. Propane combustion produces a small portion of carbon monoxide and carbon monoxide and other harmful gases, so the combustion efficiency is slightly worse than methane.

In addition, methane and propane differ in use. Because methane burns stably and cleanly, it is often used as a fuel, for example, in households as a fuel for water heaters, gas stoves, etc. Propane has a higher ignition point and higher energy density, and is mainly used in industrial fuels, oven fuels and heating.

In addition, methane and propane also have some differences in storage methods. Methane has a low gasification temperature and requires only a small pressure to be liquefied. Propane, on the other hand, has a higher vaporization temperature and requires a higher pressure to liquefy it, so storing and using propane requires stronger vessels and equipment.

To sum up, there are some differences between liquefied gas methane and propane in chemical structure, combustion mode, use and storage mode. The choice of which liquefied gas to use depends on different needs and circumstances. Whether it is methane or propane, they both play an important role in providing convenience and comfort in our lives.
